The elaboration of bioplastics from renewable polymers, such as proteins, is a field with high potential for industrial applications such as packaging, agriculture, etc. This study evaluates two different raw materials to elaborate these bioplastics by injection molding: soy protein isolate (SPI) and pea protein isolate (PPI). Both proteins are by-products, which would lower the price of processed bioplastics. However, it is necessary to control their properties in the production, so that they can replace conventional plastics. In this way, the main objective of this work was to compare the properties of SPI and PPI bioplastics processed at different mold temperatures (70 and 130 ºC). Thus, mechanical properties, transparency and water uptake capacity were evaluated. The results show the potential of these raw materials to obtain bioplastics that can replace conventional plastics, although it is necessary to choose the correct processing conditions to obtain the desired final properties.
